Abstract
The utility model belongs to an article for daily life. The utility model comprises batteries and a loudspeaker. The structural feature of the utility model is that a time delay circuit, a sound integrated block, the loudspeaker and the batteries are orderly connected; a sensor and a bias resistor present an off state; the sensor and the bias resistor are respectively connected with the time delay circuit; switches are respectively arranged on a power supply circuit and the time delay circuit. The utility model has the advantages of delayed alarm, simple structure, etc.; a urine cushion can be monitored automatically when the urine cushion is wet by the urine.
Description
This utility model is to belong to daily living article.
Because baby or patient know when to urinate wet urine pad, and are not changed timely, not only make under the weatherly, even can cause skin infection, bring certain misery to people.
The purpose of this utility model is exactly at the problems referred to above, and a kind of urine-wet alarm that can monitor the wet urine pad of urine automatically is provided.
The purpose of this utility model is achieved in that this utility model comprises battery, speaker, its structural feature is that delay circuit, audio manifold block, speaker, battery are connected successively, it between pick off and the bias resistance off-state, pick off, bias resistance are connected with delay circuit respectively, on the power circuit, be respectively arranged with switch on the delay circuit.
Major advantage of the present utility model:
1, can monitor the wet urine pad of urine automatically:
When the wet urine of urine fills up, because urine conduction, make conducting between pick off of the present utility model and the bias resistance (being no longer to be off-state between pick off and the bias resistance), entire circuit of the present utility model conducting thereupon, speaker sends sound equipment, reporting people, to urinate pad wet by urine, just can change etc.; Be beneficial to baby, patient health, also can alleviate nursing staff's physical work;
But 2 delayed alarms:
Can in a period of time behind baby's urine, (for example, about about 2 minutes) send sound equipment, inform that people change the urine pad, influence baby's normal voiding function and be unlikely;
3, simple in structure:
This utility model mainly comprises battery, speaker, audio manifold block, delay circuit, pick off, and its member is few, and assembling easily popularizes easily.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an electrical block diagram of the present utility model.
Below in conjunction with accompanying drawing concrete structure of the present utility model is described further:
This utility model comprises battery DC, speaker Y, and delay circuit, audio manifold block IC, speaker Y, battery DC are connected successively, pick off CT and bias resistance R
1Between be off-state, pick off CT, bias resistance R
1Be connected with delay circuit respectively.On the power circuit, be respectively arranged with K switch, K on the delay circuit
1
Circuit of the present utility model is arranged on the wiring board 2 on the housing 1, and housing 1 is outside equipped with pick off CT.
Audio manifold block IC, can adopt model is the audio manifold block of CW9300.
Delay circuit is by audion Q
1, audion Q
2, audion Q
3Be connected in sequence.
Pick off CT can be conductive rubber and silica gel plastics is formed.
Capacitor C
2With battery DC parallel connection, its effect is when the voltage of battery DC descends, and also is unlikely the work that influences complete machine; Resistance R
2Be audion Q
1Load resistance be again audion Q
3Base bias resistance.
Audion Q
2, audion Q
3Between be connected with resistance R
3, capacitor C
1, can determine the time constant of delaying time.
Be provided with by K switch between audio manifold block IC and the speaker Y
2The dropping resistor R of control
5, send the size of volume with this control loudspeaker Y.
At audion Q
3And be provided with light emitting diode D between the audio manifold block IC, also can making reports to the police further suggesting effect.
On and off switch K can link to each other with the interface of pick off CT, (this moment delay switch K when urine is lined with urine
1Disconnect), can report to the police.
Narrate a course of action of the present utility model below:
When the urine pad is not wet, be equivalent to resistance R
1Open circuit, i.e. audion Q
1The base stage no-voltage, this moment audion Q
1By, audion Q
2Conducting; Simultaneously with capacitor C
1Short circuit makes audion Q
3Do not work by, audio manifold block IC no-voltage, speaker Y.
When the urine pad was wet by urine, urine was with pick off CT conducting, and an at this moment suitable bias voltage is added in audion Q
1On the base stage, while audion Q
1Conducting, audion Q
2End, battery DC passes through resistance R
3To capacitor C
1Charging.Work as capacitor C
1Voltage be charged to audion Q
3Conducting voltage the time, audion Q
3Conducting, ic chip get electric work, drive speaker Y and light emitting diode D and report to the police.
